我在Android中有一个活动,包含两个元素:

编辑文本列表视图

当“活动”启动时,EditText立即具有输入焦点(闪烁光标)。我不希望任何控件在启动时具有输入焦点。我尝试了:

EditText.setSelected(false);
EditText.setFocusable(false);

没有运气。如何说服EditText在“活动”启动时不选择自己?


当前回答

真正的问题是你根本不想让它有焦点吗?或者你不希望它显示虚拟键盘,因为它专注于EditText?我并不认为EditText在开始时有什么问题,但当用户没有明确要求关注EditText(并因此打开键盘)时,打开softInput窗口肯定是个问题。

如果是虚拟键盘的问题,请参阅AndroidManifest.xml<activity>元素文档。

android:windowSoftInputMode=“stateHidden”-输入活动时始终隐藏它。

或android:windowSoftInputMode=“stateUnchanged”-不要更改它(例如,如果它还没有显示,则不要显示它,但如果它在输入活动时处于打开状态,则保持它处于打开状态)。

由于我不喜欢用与功能相关的东西来污染XML,所以我创建了这个方法,它“透明地”从第一个可聚焦视图中窃取焦点,然后确保在必要时删除它自己!

public static View preventInitialFocus(final Activity activity)
{
    final ViewGroup content = (ViewGroup)activity.findViewById(android.R.id.content);
    final View root = content.getChildAt(0);
    if (root == null) return null;
    final View focusDummy = new View(activity);
    final View.OnFocusChangeListener onFocusChangeListener = new View.OnFocusChangeListener()
    {
        @Override
        public void onFocusChange(View view, boolean b)
        {
            view.setOnFocusChangeListener(null);
            content.removeView(focusDummy);
        }
    };
    focusDummy.setFocusable(true);
    focusDummy.setFocusableInTouchMode(true);
    content.addView(focusDummy, 0, new LinearLayout.LayoutParams(0, 0));
    if (root instanceof ViewGroup)
    {
        final ViewGroup _root = (ViewGroup)root;
        for (int i = 1, children = _root.getChildCount(); i < children; i++)
        {
            final View child = _root.getChildAt(i);
            if (child.isFocusable() || child.isFocusableInTouchMode())
            {
                child.setOnFocusChangeListener(onFocusChangeListener);
                break;
            }
        }
    }
    else if (root.isFocusable() || root.isFocusableInTouchMode())
        root.setOnFocusChangeListener(onFocusChangeListener);

    return focusDummy;
}

当按下按钮时,我使用以下代码阻止EditText窃取焦点。

addButton.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        View focused = internalWrapper.getFocusedChild();
        focused.setVisibility(GONE);
        v.requestFocus();
        addPanel();
        focused.setVisibility(VISIBLE);
    }
});

Basically, hide the edit text and then show it again. This works for me as the EditText is **not** in view so it doesn't matter whether it is showing.

You could try hiding and showing it in succession to see if that helps it lose focus.

做这个,完成你的工作!

android:focusable="true"
android:focusableInTouchMode="true"

我找到的唯一解决方案是:

创建LinearLayout(我不知道其他类型的Layout是否有效)设置属性android:focusable=“true”和android:focuableInTouchMode=“true“

并且EditText在开始活动后无法获得焦点

利用其他海报提供的信息,我使用了以下解决方案:

在布局XML中

<!-- Dummy item to prevent AutoCompleteTextView from receiving focus -->
<LinearLayout
    android:id="@+id/linearLayout_focus"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:layout_width="0px"
    android:layout_height="0px"/>

<!-- AUTOCOMPLETE -->
<AutoCompleteTextView
    android:id="@+id/autocomplete"
    android:layout_width="200dip"
    android:layout_height="wrap_content"
    android:layout_marginTop="20dip"
    android:inputType="textNoSuggestions|textVisiblePassword"/>

在onCreate()中

private AutoCompleteTextView mAutoCompleteTextView;
private LinearLayout mLinearLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mylayout);

    //get references to UI components
    mAutoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.autocomplete);
    mLinearLayout = (LinearLayout) findViewById(R.id.linearLayout_focus);
}

最后,在onResume()中

@Override
protected void onResume() {
    super.onResume();

    //do not give the editbox focus automatically when activity starts
    mAutoCompleteTextView.clearFocus();
    mLinearLayout.requestFocus();
}
